LEGO 8299 Search Sub

8299 Search Sub with CD-ROM is a pneumatic submarine TECHNIC kit that also includes a CD with additional building instructions. The US version of this set, 8250 Search Sub, did not include a CD. The set has one pneumatic cylinder that operates the submarine's arm, allowing it to move and grab. The kit also has an air tank, allowing the cylinder to be operated many times without using the pump. The submarine's cockpit can be opened, allowing the pilot and his 'scooter' to get in and out. The set not only includes a minifigure, but also diving equipment for the figure. The CD contains instructions for six other models and TECHNIC building tips.

The alternate model is also a submarine, albeit with a less standard design.
